实施例
实施例1.DC009的制备和纯度确定
DC009是根据US 2016-0083423制备。将最终产物用DCM、THF和乙醚重复洗涤数次,以提高最终产物的纯度。用HPLC在以下条件下测定溶液中DC009的浓度和纯度。
管柱:烷基反相键合相管柱
流动相(MP):MP A:DI水中的0.1体积%的TFA/MP B:乙腈中的0.1体积%的TFA
检测波长:214和280nm
管柱温度:20-25℃
样品温度:10-15℃
进样体积:10-20μL
梯度:MP A和MP B。
在实施例2至6中,每种制剂的稳定性显示为“样品回收率”或“相对纯度值”。如上所述,用HPLC分析每个时间点的样品。对于“样品回收率”,%数值是通过将时间点处的DC009浓度除以T=0时的DC009浓度计算得到的。对于“相对纯度值”,%数值如下计算:(Tn时的DC009的峰面积%/T0时的DC009峰面积%)*100%。
实施例2.不同pH的溶液中的制剂稳定性
制备了表1中列出的包含10mg/mL DC009的7种制剂,将DC009溶解在每种缓冲液中,并用NaOH和HCl调节至所指示的pH。
表1.制剂T-1至T-7
制剂ID | pH | 缓冲液 |
T-1 | 4 | 5mM乙酸钠 |
T-2 | 5 | 5mM乙酸钠 |
T-3 | 6 | 5mM柠檬酸钠 |
T-4 | 7 | 50mM磷酸钠 |
T-5 | 7 | DI水 |
T-6 | 7 | 0.9%NaCl |
T-7 | 8 | 5mM磷酸钠 |
将这些制剂在40℃和60℃下储存以评估样品回收率和总杂质。表2和表3中记录了每种储存条件下的外观和稳定性。在任何样品中均未观察到沉淀。
表2.制剂T-1至T-7的外观
表3.制剂T-1至T-7的稳定性
在加速稳定性研究中,在40℃的第4天,T-1(pH 4)和T-2(pH 5)的样品回收率≥98%,在60℃为95%。在40℃的第7天,T-1和T-2在第7天的样品回收率为95%和96%,在60℃均为90%(数据未示出)。而在pH为7至8(T-4至T-7)下,制剂在60℃储存4天后的样品回收率降至90%以下,这表明杂质%显著增加。这些数据表明,DC009在酸性条件下稳定,并且在4至5之间的pH下非常稳定。对于10mg/mL的DC-009溶液,5mM乙酸钠足以维持pH 4至pH 5之间的稳定pH。
实施例3.不同pH的溶液中的制剂稳定性
在另一独立实验中,制备了表4中所列的包含10mg/mL DC009的9种制剂,将DC009溶于每种缓冲液中,并用NaOH和HCl调节至所指示的pH。
表4.制剂P1至P6
样品 | pH | 缓冲液 |
P1 | pH 7.0 | 5mM磷酸钠 |
P2 | pH 6.5 | 5mM磷酸钠 |
P3 | pH 6.0 | 5mM柠檬酸钠 |
P4 | pH 5.5 | 5mM柠檬酸钠 |
P5 | pH 5.0 | 5mM乙酸钠 |
P6 | pH 4.0 | 5mM乙酸钠 |
P7 | pH 3.5 | 5mM乙酸钠 |
P8 | pH 2.0 | 5mM乙酸钠 |
P9 | pH 1.0 | 5mM乙酸钠 |
将这些制剂在60℃下储存以评估样品在不同pH下的稳定性。所有制剂中的DC009的相对纯度值记录在表5中,DC009的纯度定义为在T=0时为100%。数据表明,DC009在所有酸性条件下(pH<7)都是稳定的,并且在60℃下持续10天保持纯度>95%。在60℃下保存一个月(第38天)后,DC009在pH 1至pH 6下是稳定的,并保持>86%的纯度值。在pH 2.0至5.5下显示出最佳的稳定性。
表5.制剂P1至P7的稳定性(相对纯度值)
*相对纯度值:(Tn时的DC009的峰面积%/T0时的DC009峰面积%)*100%
实施例4A.不同赋形剂中的制剂稳定性
制备了表6中列出的包含10mg/mL DC009和不同量的赋形剂(mg/g)的6种制剂,每种制剂均用NaOH和HCl调至pH 4.5。将这些制剂在40℃和60℃下储存以评估样品回收率和总杂质。稳定性数据总结在表7中。
表6.制剂E1至E6
成分(mg/g) | E1 | E2 | E3 | E4 | E5 | E6 |
DC-009 | 10 | 10 | 10 | 10 | 10 | 10 |

EDTA2Na 2H<sub>2</sub>O | 0.055 | 0.055 | 0.055 | 0.055 | 0.055 | 0.055 |
甘氨酸 | 22 | |||||
乳糖 | 90 | |||||
甘露醇 | 50 | |||||
二水合海藻糖 | 90 | |||||
蔗糖 | 90 |
表7.制剂E1至E5的稳定性
在加速稳定性研究中,60℃下2周时E2至E5的样品回收率≥90%(表7)。E1的甘氨酸赋形剂与对照E6相比显著降低了稳定性,而甘露醇、海藻糖、蔗糖和乳糖与对照E6相比改善了稳定性。
实施例4B.不同赋形剂中的制剂稳定性
在单独的实验中,测试了表8中列出的不同赋形剂的DC009稳定化效果。对于制剂S1至S10,在5mM乙酸钠缓冲液中制备10mg/mL DC009,每种赋形剂的浓度为3.8%,并且将制剂的pH调至pH 4.5。将这些制剂在60℃下储存两周。表8中记录了全部制剂中DC009的相对纯度值,将T=0时的DC009纯度定义为100%。60℃下2周时S1和S3的纯度水平>80%。结果表明,甘露醇和山梨糖醇与其他赋形剂相比提供了更好的稳定性。
表8.制剂S1至S10的稳定性(相对纯度值,%)

S10 | 组氨酸 | 100.00 | 88.76 | 78.86 | 69.85 |
实施例5.含有甘露醇的制剂的稳定性
制备了表9中列出的包含10mg/mL DC009的4种制剂,每种制剂用NaOH和HCl调至pH4.5。M1至M3包含50mg/g D-甘露醇,而M4不含D-甘露醇。将这些制剂在40℃和60℃下储存以评估样品回收率。表10记录了每种储存条件下的稳定性结果。
表9.制剂M1至M4
成分(mg) | M1 | M2 | M3 | M4 |
DC-009 | 10 | 10 | 10 | 10 |
无水乙酸钠 | 5mM | 5mM | 5mM | |

表10.制剂M1至M4的稳定性
在加速稳定性研究中,60℃下2周时M1至M3的样品回收率≥90。数据表明,与没有甘露醇的M4制剂相比,添加甘露醇改善了制剂稳定性。
实施例6.冻干制剂的制剂稳定性研究
制备了表11中列出的2种制剂。将每种制剂在冻干机中冻干,并在25℃和40℃下储存以评样品定回收率。表12总结了每种储存条件下的稳定性结果。
表11.冻干制剂
